Pls help I’m really confused I’ll give you 35 pints Find the total payment,
given the cost, sales tax
rate, and tip rate.
Cost: $35.75
Sales Tax Rate: 5%
Tip: 15%

The total payment is thus $35.75 plus $7.11, or $42.86

Step-by-step explanation:

Note that the sales tax doesn't affect the tip.  The sales tax is 5% of the cost and the tip is 15% of the before tax cost.  We calculate the tax and the tip separately, then add them together and finally add this sum to the cost.

Sales tax:  5% of $35.75:  $1.75

Tip:  15% of $35.75:  $5.36

Adding these two quantities results in $7.11.

The total payment is thus $35.75 plus $7.11, or $42.86

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
